5 could be for some other guys like Froch, Donaire, Wladimir, Abner Mares, etc ... All these guys deserve a #5 spot a lot more than Broner.

And about Ring well that list is absolute crap, I don't know how beating DeMarco is better than beating all the guys Abner has been beating (Moreno, Agbeko x2, Vic) or Froch (Bute, Johnson, Abraham, Dirrell, Taylor)
